Description
Technical field
The present invention relates to hot pipe technique field, more particularly, to a kind of heat pipe and its finned tube of efficient radial direction heat transfer.
Background technology
The current mineral matter energy is increasingly short, the severe destruction that human residential environment also suffers from, especially greenhouse gas emission,
Caused environment for human survival problem is also increasingly highlighted, and earth temperature on average rises, and glacier is gradually reduced thawing, and sea level is continuous
Rise, island country is just jeopardized step by step, threaten the safety in coastal cities, this has been indisputable fact.The increasingly serious haze of China
Problem cannot be solved for a long time, and it is healthy to have a strong impact on people, people is suffered from lung cancer probability and is substantially increased, and haze phenomenon is serious
It is difficult to fundamentally be resolved, reason is that China's process of industrialization is accelerated, to the increasing institute of the waste gas of airborne release
Cause, and nature lacks in spontaneous factor residence in itself.We are it is also known that the energy that the mankind are used almost has 80% above is needs
By the process that heat energy is changed, heat energy conversion equipment relies primarily on heat transmission equipment to realize.The many activities of the mankind and production are real
Trample and all be unable to do without the energy, and the most of energy of China come from the mineral matter energy, mineral matter energy resource consumption can be produced to be caused to environment
Unfavorable gas discharge.Thus China does one's utmost to advocate to development of clean energy and utilization, while researching and developing energy-saving equipment energetically
New Products ＆ New Technology, and heat energy conversion equipment surely belongs to the most key equipment of energy-saving and emission-reduction.Heat pipe is just belonging to this High Efficiency Thermal
One of energy conversion equipment, and it is very wide using face, it is mainly used in steam power plant, smeltery, food chemistry, medicine, production of construction materials
Enterprise etc..Capillary siphoning form heat pipe is used from the past, gravity type heat pipe today is developed into, then to bushing type radial direction heat transfer type
Heat pipe and magnetic force heat pipe etc., species is various, can be divided into by structure type：General heat pipe, separate heat pipe, capillary blowback
Road heat pipe, micro heat pipe, flat-plate heat pipe, radial heat pipe etc..Inventor notices that radial direction heat transfer type heat pipe has many tradition weights
The incomparable advantage of power formula heat pipe, from the point of view of existing product service condition, bushing-type heat tube not only has low production cost, its
Heat exchange efficiency is 1.2 times of Conventional gravity heat pipe, although the patent of invention of sleeve pipe radial direction heat transfer type heat pipe has had more than ten both at home and abroad
It is individual, but find no three layers of bushing-type heat tube.
It is understood that heat is transmitted at low temperature from high temperature, the temperature difference is the power of heat transfer, and people's production practices are all
It is desirable to heat energy to be transmitted towards another medium direction from a medium or from one end to the other side transmitted, with specified property and target
Property, because thermal molecular motion does not possess directionality, we make molecule heat energy transmit towards me as far as possible in heat transfer process
Need direction to transmit, must just reduce the homonymy medium temperature difference, increasing both sides needs the mean temperature difference of thermal energy exchange, and this is favourable
It is also to meet field-synergy theory in heat exchange, field-synergy theory teaches that：When two fluids use countercurrent heat exchange method,
If velocity field cross-sectional uniformity is consistent, also temperature gradient field exchange heat cross section it is equal in magnitude when, its temperature gradient field and
The vector included angle cosine value of velocity field goes to zero, then field coordination is optimal, and its heat exchange efficiency is also optimal.So
We become to make homonymy hot-fluid to weaken at a heat exchange form of trying one's best, and heteropleural heat exchange hot-fluid is maximized, because thermal molecular motion is that do not have
Directionality can say, cannot also go to prevent homonymy to cause heat energy to select unhelpful homonymy direction to transmit by the temperature difference, only optimize both sides
Fluid-flow mode, makes temperature gradient field tend to uniformity, so as to win maximum heat exchange efficiency.
The content of the invention
The technical problem to be solved in the present invention is directed to prior art deficiency, according to field-synergy theory, there is provided one kind heat exchange
The heat pipe of the maximized efficient radial direction heat transfer of efficiency.

Heat pipe one end be used for realize double-deck inner tube homonymy with working media countercurrent flow；The working media of the double-deck inner tube can be with
It is water, the circular passage work medium for heat pipe is one or more medium such as water, freon, methyl alcohol, acetone, oil.
The circular passage heat pipe is better than existing heat pipe adiabatic section structure type, and forms evaporator section encirclement condensation segment structure
Mode, is allowed to become compacter, it is possible thereby to rapid phase transition heat transfer type around here is absolutely realized, by vaporization absorption latent heat
Condensation release latent heat is arrived again, and this realizes that heat transference efficiency is much higher than heat-conducting mode, and latent heat treatment is with latent heat absorption process
Transition formula realizes the transfer of heat, and general heat conductor heat transfer type is incomparable, is hardly the heat transfer of an order of magnitude.
Preferably, the second layer inner tube is that working media enters pipe, and the second layer inner tube two ends are hatch frame, institute
Ground floor inner tube is stated for working media efferent duct, one end of the ground floor inner tube is that hatch frame is exported for working media,
The other end is enclosed construction.
Further, thermal insulation layer is additionally provided between the ground floor inner tube and second layer inner tube, the thermal insulation layer is by being incubated
